That’s what we are doing next. We have tested this internally with 2 boxes on the LAN connected to a single ESX server and verified data is going back and forth in a speedy fashion but that’s all over 100MB. Im going to flip to protocol A and drop this on a T1 wan link and see how it goes. I saw a couple of searches turn up wan-proxy but I didn’t truly understand what was being discussed and why. I will look into it.

While you're still testing, I would make sure you test what happens with
extended writes to the primary when the secondary is on the other end of
a slow link.. You might find that buffers and queues can get full, and
impact performance on the primary..
I think I saw something recently about a wan proxy setup the they're
working on. I would guess
that using that is the best way to go for your setup...

It seems to me that you *just* told many people about it :-)
